Proof Coil Chain
A welded link chain. Chain size is designated by the diameter of the steel used in making the links (e.g.. 3/16"-3/4"). Made from low carbon steel, proof coil is a general utility chain for such uses as tie-down, log chain and assembly tow and switch chain. Available in plain, hot galvanized, and bright zinc finishes.

Load or Chain Binder
This devise consists of a handle, two offset links and grab hooks which, when connected to a section of the load-binding chain and the handle pulled, tightens the chain.

Grab Hook
Grab hooks are designed to hook over a chain link and will hold fast when the chain is tightened.

Winch
A ratcheting device used to tighten a rope or lashing strap.

Lashing Strap
Used for securing loads. Not used for securing heavy equipment. Typical polyester or nylon strap strength is 10,000-20,000 pounds. Smaller straps are available with a built-in winch. Larger straps are designed to be used with winches mounted on the truck bed.

Chain Hoist
Sizes are available from 1/2 to 5 ton capacity.

Rope Thimble
Used to protect the eye in a rope or cable.

Wire Rope
To coil or uncoil, roll the rope like a steel hoop.
![Page 16: Proof Coil Chain](https://reader035.vdocument.in/reader035/viewer/2022062302/568165db550346895dd8eccb/html5/thumbnails/16.jpg)
Twisted Polypropylene Rope
Keep away from flames and hot metal, it will melt or solidify and break easily. Also called trucker's rope which is generally black with an orange stripe.

Nylon Rope
Maybe manufactured as a laid (twisted) rope or a braided rope. Stronger and more expensive then poly rope. Braided rope does not have individual strands therefore it is not suited for hand braiding.

Manila Rope
This is a laid (twisted) and comes in three and four strands. A natural fiber, manila is stronger than cotton, but weaker than the synthetic ropes.

Cotton Rope
Cotton ropes are soft but the weakest of the natural fiber ropes.
